What is the Spam Risk Score?
How likely your emails are to hit spam filters — separate from whether they bounce.
The spam risk score is a number from 0 to 100 that estimates how likely emails sent to this domain are to be filtered by spam engines. Lower score = higher spam risk.
This is different from the deliverability score. Deliverability tells you whether an email will bounce. Spam risk tells you whether your emails will reach the inbox at all.
How to read it
| Score | Rating |
|---|---|
| 75–100 | Low risk — clean domain signals |
| 50–74 | Moderate — some signals missing |
| 25–49 | High risk — significant gaps |
| 0–24 | Very high risk — likely to be filtered |
What affects the spam risk score
The score starts at 100 and deductions are applied for each signal:
- No SPF record → −25 points
- No DMARC record → −20 points
- No MX records → −35 points
- Permissive SPF (+all or ~all) → −15 points
- New domain (under 90 days) → −20 points
- Free email provider → −8 points
- Catch-all domain → −5 points
- Disposable domain → score immediately set to 5
Why it matters
If you're sending outbound campaigns, domains with poor spam risk scores have aggressive spam filtering — even valid, delivered emails may never reach the inbox. Use the spam risk score to prioritise warm, well-configured domains.
